runPluginVerifier: release 2020.1 seems to be resolved to build 202.7660.26 rather than 201.6668.121

[PawelLipski]

See https://github.com/VirtusLab/git-machete-intellij-plugin/pull/637/files for a sample PR where this happens.

Full build logs can be seen under https://app.circleci.com/pipelines/github/VirtusLab/git-machete-intellij-plugin/3675/workflows/8c46c821-3518-4a1b-be9e-c03268609d37/jobs/3851 , step Verify binary compatibility with supported IntelliJ versions (failure of this pipeline is expected and not related to this very issue).

First we get:

2020-10-29T18:41:08 [main] INFO  verification - Reading IDE /root/.pluginVerifier/ides/IC-2020.1
2020-10-29T18:41:12 [main] INFO  verification - Reading IDE /root/.pluginVerifier/ides/IC-2020.1.4
2020-10-29T18:41:15 [main] INFO  verification - Reading IDE /root/.pluginVerifier/ides/IC-2020.2.3
2020-10-29T18:41:18 [main] INFO  verification - Reading IDE /root/.pluginVerifier/ides/IC-203.5251.39

which is expected, but later the actual verification runs against:

Scheduled verifications (4):
com.virtuslab.git-machete:0.8.1-32-SNAPSHOT+git.a833b4c against IC-202.7660.26,
com.virtuslab.git-machete:0.8.1-32-SNAPSHOT+git.a833b4c against IC-201.8743.12,
com.virtuslab.git-machete:0.8.1-32-SNAPSHOT+git.a833b4c against IC-202.7660.26,
com.virtuslab.git-machete:0.8.1-32-SNAPSHOT+git.a833b4c against IC-203.5251.39

so 201.6668.121 (2020.1) seems to be missing and, surprisingly, replaced with one more instance of 202.7660.26 (2020.2.3)... which also happens to be the version against which the plugin is being built.

Ok, it appears that there's an issue with the service that resolves IDE download URLs - for major versions, like 2020.1, there's the latest stable returned - 2020.2.3 as for now.

Anyway, I've got in touch with the team lead responsible for that and I got also confirmation, that some IDEs are removed i.e. due to security reasons: WS-2019.1.2, PY-2019.1.2 + all major releases, so 2020.1 is not present on CDN anyway.

Please keep in mind that these versions are not listed within the Marketplace dashboard as well:

I'll try to find out the best way to provide an up-to-date list of the IDE versions available for testing with the Plugins Verifier.

[PawelLipski]

Ok! good to know, thanks :)
This implies that possibly caring for compatibility with 2020.1 specifically isn't that important... also, are there any guarantees by design like if, for the given release A.B (e.g. 2020.1), plugin is compatible with any A.B.C (e.g. 2020.1.4), then it's compatible all A.B.*?

[hsz]

Minor releases introduce rather bug fixes and should not introduce breaking changes like the method signatures modifications of the 2020.1.

FYI: there's Incompatible Changes in IntelliJ Platform and Plugins API section in SDK Docs available that utilizes all breaking changes introduced in time.

[hsz]

The proper fix is provided. When there'll be a source of truth available regarding the available IDE versions that can be provided to the Plugin Verifier, it'll be linked within the stack trace and documentation.

[PawelLipski]

@hsz is there an ETA for v0.6.2 that would include this fix? ;)

Also trying to add 0.7.0-SNAPSHOT seems to not work. Last few snapshots here are missing the jar file: https://oss.sonatype.org/content/repositories/snapshots/org/jetbrains/intellij/plugins/gradle-intellij-plugin/org.jetbrains.intellij.plugins.gradle-intellij-plugin/0.7.0-SNAPSHOT/

The list of the available products that can be used for testing is here: https://jb.gg/intellij-platform-builds-list

[AlexPl292]

Wow, cool! What is the proposed usage of this link? Just open it and find the products or there is some integration with the plugin?
Also, I may be wrong, but last time I've tried to check against 2020.2.1, 2020.1.2, and 2020.1.1 they were unavailable, but they are presented in this list.

Probably shortened URL is not yet refreshed - valid target URL is:

https://data.services.jetbrains.com/products?fields=code,name,releases.downloads,releases.version,releases.build,releases.type&code=DG,PS,DL,MPS,MPSIIP,RDCPPP,WS,AC,IIC,IIE,GO,CL,PCD,PCC,RD,PCE,IIU,RM,PCP

That's a raw dataset from the data.services - the quickest solution I could provide for the listing of available product versions.
Each item contains, i.e.:

    }
  },
  version: "2020.1.3",
  build: "201.8538.31"
}

The downloads property points out that the version is available via CDN - but we're not going to rely on these URLs.

If type is release - use 2020.1.3, otherwise - build property should be used.

v0.6.2 is now available.
